I am guessing from the Hanzi text in the notes section that the
definition I had entered was "permanent, everlasting" which I had
deduced from Google Translate. Now that definition is
lost.

This was a word that I had added in lesson 10.3. Now if I
look at that lesson, none of the Pinyin words are highlighted.
However, the entire Hanzi sentence is highlighted with the
definition being the English for the entire sentence. This
defeats the whole reason I was using vocabulary in the first place.
I like being able to enter individual words so I can hover
the mouse over the word and see its meaning. Now it seems that
everything is lost.

I just tried adding a vocabulary word to see what happens, i.e.
highlight and fill in the form and it is extremely slow and it
won't let me fill out the form. The old behavior was very
useful. The current behavior is retrograde.

If our old vocabulary lists can't be restored, I would prefer to
delete all and start over. However, I'll only do that if the
older behavior is restored.
